I'm glad Sulu is gay. I'm tired of gay fans of the show being promised one day they'll be represented on Star Trek, only for it to be pushed back, and back, and they get nothing out of it. Finally, one of the main cast, and not a special "I'm gay" actor role that will be shown in this movie and whisked off never to be seen again, is gay, and they will be loved and accepted by the rest of that main cast, and they will be treated like human beings.
If that's not what Gene Roddenberry wanted, if that's not what he was about, then it's his loss. He has been dead for 25 years. Society needs to move forward. Star Trek should represent that very idealism. Good work, Simon.
